Given numbers are 563, 646, 756, 161

The list of prime factors of all numbers are

Prime factors of 563 are 563

Prime factors of 646 are 2 x 17 x 19

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 161 are 7 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 563, 646, 756, 161

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(563, 646) = 363698

GCD(563, 646) = ( 563 x 646 ) / 363698

= 563 / 646

= 563

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 563, 646, 756, 161 is 1
